My money is on the motor mounts.

A slight miss a big sign of a bad engine wiring harness, especially since so many are bad between '93 and '95.

Have your tech examine the wiring harness for cracking insulation.

I don't know why he's focusing on a fuel supply / pressure problem, which doesn't seem characteristic of this at all.

I would have focused on an ignition-related problem - a bad plug, plug gap too small, but probably a bad spark plug wire, or a short at the spark plug wire resistor "boot" or end. A bad connection at the resistor boot would be my guess for the missing, if the engine wiring harness is fine.
